What do you mean? Digitizing doesn’t increase the precision of anything, it always loses precision. I don’t think you’re summarizing that paper accurately, they are most certainly talking about using analog compute units, specifically analog matrix-vector-multipliers, and a method for increasing the analog signal precision before digitizing the signal. The components used are analog compute circuits, and the title of the paper has “analog” in it. This is absolutely relevant to what I was trying to say because RNS is used here to make multiple analog data lines representing a value provide increased precision compared to a single analog data line.
- corethree 3y agoNo they digitize the signal to get the modulos. Look at the diagram. It's not relevant because there are digital operations need to get the final result BEFORE they do the final ADC conversion. It's like saying analog transistors are used to make digital gates therefore are all computers with gates are analog. They are talking about an analog MVM in a system that is doing hybrid computations both digitally and with analog systems. It completely fails to support your point of increasing precision in an analog computer with multiple analog signals. It's basically the same thing as using one analog signal per digit instead they're using one signal per modulo.
